title: Nanowire photovoltaic efficiency enhancement using plasmonic coupled nano-fractal antennas.
abstract: We suggest the use of nano-fractal antennas for plasmonic coupling to enhance nanowire (NW) photovoltaic power conversion efficiency. Silicon radial pn junction NWs positioned inside Apollonian and Sierpinski nano-fractal antennas are simulated with different topologies and NW lengths. An enhancement in power conversion efficiency ranging from 12% to up to 24% over the same NW without antenna case is achieved.
